This question reminded me of one of my own. I want to create an alias that will ssh to a machine, runs a command (in this case, cd to a provided path) and then gives me a shell. I've run a hundred variations of this:

$ ssh user@machine 'cd /some/path/ && bash -i -l'

which is about the best I can do. It gives me a bash prompt in the right directory, but without job control and without the ability to use arrow keys (and some other shortcuts). Is there an easy way to do this?

I can't do this easily at the end of my bashrc or profile, because the path I want to go to will vary (I'll pass it as an argument to the alias) and occasionally, I'll even ssh to that machine without wanting to go anywhere weird at all -- home directory is fine.

Look at the sshd man page, Authorized_keys File format section. Inside it has the option command="command" which is what to do when that key connects. The original included command for the connection is included in a variable.

You might be able to set this command to run bash with a startup script that checks the original command value and runs it, then leaves you in an interactive shell.

The problem is that /some/path/ isn't always the same and sometimes I ssh to the machine and want to just be in my home directory like normal. I'll add that info to the question.

taking the manpage literally, I think it's either a command, or a proper interactive shell
